Question

I REALLY need HELP Please!! see attachments

Answer 1

find the slope, write your equation in standard form, then convert it to slope intercept form

i'll give you a tip, the equation is >

Answer 2

how to convert them this is giving me trouble its very hard

Answer 3

lol rob.

Answer 4

so is it (3/2) =x

Answer 5

Use rise/run to find the slope. It goes up 3, and over 5.

Answer 6

oh so is it the same but with five

Answer 7

yep. So your slope, \(m = \cfrac{3}{5}\)

Answer 8

so how do i get the answer form there

Answer 9

You have your slope now, and you need to use one of your points to plug it into slope-intercept form \(y=mx+b\)

Answer 10

The formula for a slope intercept is y=mx+b

Answer 11

The b is where the y axis is and the m is the slope.

Answer 12

y=(3/5)5x

Answer 13

If the slope is going to the left side it's a negative integer. If the slope is going to the right then it is a positive integer.

Answer 14

so its positive

Answer 15

If the slope is negative, it's decreasing, therefore it's a decreasing function, vise versa.

Answer 16

Therefore this slope is positive, and so it's an increasing function, because we're counting ?UP 3, and over 5.

Answer 17

Now for your problem it is meaning that the 3/5 is the coordinates of (3,5) and the 5 is the x axis.

Answer 18

Remember that the number before the x is the coordinates.

Answer 19

y=>3-5

Answer 20

Y= 3/5

Answer 21

y=>3/5-5x

Answer 22

You don't change the x position.

Answer 23

im sorry this is very difficult for me

Answer 24

You have your point \((0,\color{green}{-3})\) and \(\large \color{red}{m=\frac35}\) plug these points into your equation. \[\large y=mx+b\]\[\large y=\cfrac{3}{5} x -3\]

Answer 25

But you can use the distributive property for this.

Answer 26

@calculusxy , what do you mean by this? "Now for your problem it is meaning that the 3/5 is the coordinates of (3,5) and the 5 is the x axis."?

Answer 27

would that be the answer Jhanny

Answer 28

Since you have 3/5x-5 you multiply both sides by 5 like (3/5*5) and (5*5). Then you would get 3x-25

Answer 29

That way you get rid of the fraction to make it easier.

Answer 30

3.5 is the slope, the distance between the two points (0,-3) and (5,0)\[\large m=\cfrac{y_2-y_1}{x_2-x_1} = \cfrac{0-(-3)}{5-0} = \cfrac{3}{5}\]

Answer 31

and yes, @darkzii , do you somewhat understand how i got there?

Answer 32

yes i do

Answer 33

so the answer is y=3/5x-3

Answer 34

you converted them into the answer right

Answer 35

Yes

Answer 36

You converted the fraction from 3/5 to 3 to get the slope.

Answer 37

so theres no greater than or equal to in this equation or less than or equal to?

Answer 38

just equals

Answer 39

It is all a specific answer.

Answer 40

I've made a mistake it seems. Lets try this. Lets FIND the y-intercept. we use (0,-3) and m=3/5\[\large y=mx+b\]\[\large \color{red}{-3}= \cfrac{3}{5}\color{red}{(0)} +b\]\[\large b = -3\]Now we've found our y-intercept. We've now got our y-intercept, \(b=-3\) and our slope.\(m=\cfrac{3}{5}\) plug it into the form, \[\large y=\cfrac{3}{5}-3\]

Answer 41

That's what @darkzil wrote as his slope.

Answer 42

forgot the x.

Answer 43

y=3/5x-3*

Answer 44

Yes darkzil wrote that before in a reply.

Answer 45

Also, we can use our other point to find the y-intercept as well, \((5,0\)).\[\large y=mx+b\]\[\large 0=\cfrac{3}{5}(5)+b\]\[\large 0=3 + b\] \[\large b=-3\] Just showing how you can use either point to find your y-intercept.

Answer 46

@darkzil Did you find the answer to your problem?

Answer 47

yes i did thank you guys

Answer 48

No problem!!! :)

Answer 49

And from your graph shown, I believe your function wuld look like \[\large y \ge \cfrac{3}{5}x-3\]
